Cassel Ruzzarin Advogados

What Cassel Ruzzarin Advogados does

Cassel Ruzzarin Advogados is a Brazilian specialist law firm founded in 2011 and headquartered in Brasília, exclusively dedicated to the defense of public servants (servidores públicos). The firm operates across four office locations — Brasília, Rio de Janeiro, Belo Horizonte, and Recife — serving individual public servants at federal, state, and municipal levels as well as the unions, federations, and associations that represent them. Its practice spans the full career lifecycle of public servants, from civil service exam entry through retirement, covering administrative litigation, social security planning under both the RGPS (INSS) and RPPS regimes, union law and collective bargaining, and representation before the TCU and superior courts (STJ/STF).

The firm's product surface is organized around nine core practice areas and several specialized service modules (INSS adjustment, planning, benefit granting, and reviews, plus RPPS/RGPS reciprocal counting). Underpinning delivery is a set of digital platforms including the Portal dos Clientes (client portal), the weekly Newsletter Servidor, the Info Greve strike-information portal, and the Portal do Cidadão for social security questions. Content marketing is conducted via YouTube, WhatsApp, and external publications in outlets such as Congresso em Foco, Migalhas, and ConJur. No proprietary AI or technology products have been disclosed; the firm operates as a partner-led professional services business with 59 staff.

Revenue is generated through professional services fees, quoted and negotiated per case; no public pricing is disclosed. The go-to-market combines sales-led direct legal service delivery with a community-led motion built around long-term counsel relationships with unions and federations such as FENAMP, FENAPRF, SINASJUDFEGO, SINPRFGO, SINPOJUD BA, SINTRAJUD, SINTUFRJ, and SITRAEMG. Ownership is a private partnership among the founders (Rudi Cassel and Aracéli Rodrigues) and additional partners, with no external investment, private equity, or institutional investor involvement.
